Abstract: Systems and methods are provided to determine an estimated location of a user equipment (UE). For instance, a UE can provide a positioning request to a node while the UE is in a radio resource control idle (RRC_IDLE) or inactive (RRC_INACTIVE) state. The positioning request can be implemented in a random access channel (RACH) message A (MsgA). The UE can then receive a positioning response from the node. The positioning response can be implemented in a RACH message B (MsgB).

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.

Abstract: Methods and systems are provided for communicating in a wireless network based on a prioritization status. User equipment can receive a first signal that includes an indicator. The UE can determine a prioritization status for a second signal based on the prioritization indicator. The UE can communicate, with one or more radio access networks (RANs) of a network, the second signal, where the timeline of the second signal can be out of order respective of other signals communicated by the UE and the wireless network. The second signal can include data transmitted by an ultra-reliable low latency communication (URLLC) service. The UE can communicate the second signal out of order with respect to one or more additional signals. The UE, based on the indicator, can communicate hybrid automated repeat request (HARQ) feedback before a HARQ feedback timeline of a non-urgent transmission.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing beam failure recovery. An embodiment operates by detecting a beam failure on a secondary cell (SCell). The embodiment transmits, to a base station, a beam failure recovery request (BFRQ) for the SCell over a primary cell (PCell). The embodiment transmits the BFRQ for the SCell over a Primary Uplink Control Chanel (PUCCH), a Physical Random Access Channel (PRACH), or a Primary Uplink Shared Channel (PUSCH) over the PCell. The embodiment can transmit a schedule request (SR) to allocate a PUSCH over the PCell. The embodiment receives, from the base station, a response for the BFRQ for the SCell over the SCell or the PCell. The embodiment then uses a new beam for the SCell based on the response for the BFRQ for the SCell.

Abstract: Some embodiments of this disclosure include apparatuses and methods for providing semi-static integrated access backhaul (IAB) resource configurations in an IAB network. For instance, a central unit (CU) of an IAB donor can provide, to a distributed unit (DU) of an IAB node, F1 application protocol (F1AP) signaling data indicative of a semi-static IAB resource configuration regarding at least one of downlink resources, uplink resources, or flexible resources. The semi-static IAB resource configuration indicates whether the at least one of downlink resources, uplink resources, or flexible resources are hard resources, soft resources, or not available resources. The CU can further provide, to a mobile termination (MT) of the IAB node, radio resource control (RRC) signaling data indicative of the semi-static IAB resource configuration.

Abstract: A method and device are disclosed for performing collision resolution in a two-step random access channel (RACH) process. In such a process, an MsgA PUSCH signal and a grant based PUSCH signal may collide. When such a collision is detected, either the MsgA PUSCH signal or the grant based PUSCh signal are dropped. The other of the two signals is then transmitted. The determination regarding which signal to drop can be based on a set of rules stored in memory.

Abstract: Methods and apparatus are described for methods and apparatus for carrying out wireless communication using Long Term Evolution (LTE) in a frequency band with low peak-to-average-power. The approach includes precoding, in the frequency domain, a plurality of physical channel signals, followed by multiplexing, where the procoding is performed according to predetermined codes with a code length selected based on a length of an entire signal of the multiplexed precoded plurality of physical channel signals. In addition, the approach includes being configured to map the multiplexed precoded plurality of physical channel signals to subcarriers in the frequency band, as well to generate a time domain waveform based on the mapped signals.
